We examine how investor demand for leverage shapes asset management fees. We show that in the sample of U.S. equity mutual funds: (1) fees increase in fund market beta precisely for beta larger than one; (2) this relation becomes stronger and high-beta funds experience larger inflows when leverage constraints tighten; and (3) low net alphas are especially common among high-beta funds. These results are consistent with a model in which asset managers compete for leverage-constrained investors with heterogeneous risk aversion. The asymmetric relation between betas and fees also extends to the HML and SMB factors.

Take the recent study by Chen Lin and Mingzhu Tai from the HKU Business School, conducted with collaborators from the University of California, Berkeley and the Chinese University of Hong Kong. Their paper addressed a fundamental worry for almost everyone during the pandemic: Money. Specifically, they examined how people in the U.S. saved money in response to COVID-19.
